However, I am now having a second problem. For those who are not familiar with Tumblr, when one is logged in and goes to a blog that is not their own, there are buttons that appear in either the upper or lower (depending on the theme) right corners of the page, like this: http://i905.photobucket.com/albums/ac254/unholycow/supposedtolook_zps9074a183.jpg These are supposed to show up NO MATTER WHAT BROWSER IS BEING USED. ON EVERY BLOG. Be it Firefox, Chrome (what was used here, and therefore is obviously working), Internet Explorer, whatever...they're supposed to show up. And until at least a couple of hours ago, they WERE showing up. However, now when I go to pages on Firefox, they look like this: http://i905.photobucket.com/albums/ac254/unholycow/notsupposedtolook_zps1e14f35d.jpg Note that the buttons that were showing up in Chrome are missing here.

I have tried reinstalling Firefox, resetting it, starting it in Safe Mode, restarting my internet connection, and restarting my computer, and none of this has solved the problem...either problem. The buttons still aren't showing up. I don't know if this is a problem on Tumblr's end, or a problem on Firefox's end, but obviously something is wrong here, and- judging by the fact that things work fine in other browsers- the problem probably isn't with my computer itself.

This problem is very upsetting to me for many reasons:
-First off, all of my bookmarks are stored on Firefox...which means all the blogs I go to for frequent reblogging (for those who aren't familiar with the concept- look it up, I dunno how to explain it) are saved on Firefox. Chrome's Favoriting/Bookmarking system is very unwieldy and I never quite got the hang of it...it doesn't look like Firefox's bookmark menu, and it doesn't appear to work like Firefox's bookmark menu. I have no idea how to use it.
-Seeing as how all other sites are working on Firefox, except Tumblr, that means I would be going to Chrome JUST for Tumblr. And...I really, really don't like that. Because in addition to having all of my bookmarked sites here, I would be going to Chrome for one single thing. Besides the fact that I despise Chrome and IE, there's the fact that I would rather have one browser and be able to do all those things on that browser, without having to go to another one.
-My Firefox is version 22...the most recent version. It has been that version for WEEKS. Weeks, and I have not had this problem until today. While I do make use of Add-ons, the fact that I started this in safe mode, and reset it as well (and as of this typing, I still am in the default mode), shows that Add-ons are not the issue here.

So...can someone give me some idea as to what is going on here?

EDIT: Apparently Photobucket isn't working for some. Here are some imgur versions of the same screenshots:
Here is how it is supposed to look...done on Chrome, because it's working there: http://imgur.com/21dei4i
How it looks in Safe Mode/Default/whatever Firefox: http://imgur.com/sdcv7da

EDIT 2: Despite the fact that someone tagged a Helpful Reply...said reply DID NOT WORK. I do apologize for not writing that in my OP, but that was another thing I tried.
ALSO, I checked the Firefox tag on Tumblr, and it appears other Firefox users are having the same kind of trouble: http://www.tumblr.com/tagged/firefox

I'm getting pretty sick of it because I thought I was going to get away from pop-ups on firefox...

Some of these problems are due to unwanted software creating scheduled tasks. Besides the initial replies you may wish to look particularly at comments in this thread by by resident expert troubleshooter jscher2000 that summarise the current knowledge. Including

Firefox will not open. I tried every single troubleshoot recommendation, and it still won't work. I thought it may be under the "corrupt profile data" troubleshoot article, but when I followed the recommendations to change to a new profile, the profile manager would not open or run on my computer--as if it never existed. I tried downloading a different browser, and as soon as I imported my firefox data, it started misbehaving in the exact same way.

Why do I persistently get this particular script error that makes my browser hang for dozens of minutes?

chrome://global/content/bindings/tabbox.xml:73

It has nothing to do with any of the extensions or plug-ins I have activated. The only ones I ever have activated almost all of the time are Status-4-Evar in the Extensions category, and Adobe Acrobat in terms of Plug-ins. Both of these are up to date. It's also not about hardware acceleration, I don't believe, because I've disabled that feature in my options.

No, the error seems to pop up when I'm dealing with "busy" webpages with a lot of graphics and such. I've tried all of the little tricks they have here in the help, and it's still not stoping the script. I use to get a similar perisistent script error on older versions of Firefox.

A little help, por favor, to solve this once and for all, because I know I'm far from the only one experiencing this.

When I perform a single word search in the firefox address bar, such as 'asdf', 'google' 'test', i get rediredted to sitecrafting.com At first a web logo for sitecrafting shows up but my single word search is still in the address bar. Then after a second or two the sitecrafting.com address appears in the address bar and the screen refreshes to the sitecrafting.com website.

However, if i do a multiple word serch in the address bar, then i get a google search as expected. For instance 'asdf asdf' give me a google search results page for that two worded phrase.

I have done the keyword.url reset. I have uninstalled firefox and removed all profile/preference and then reinstalled. I have tested in safe mode with all addons disabled. None of these have fixed the problem.

Going from a secure page back to a non secure page I am constantly getting this warning. I had it disabled in the config page but it has now come back. I dropped IE for Firefox but if I have to put up with this it's Bye Bye Firefox.

Hello,
I have been having the Unresponsive Script warnings for what is probably going on a year or so now, and it's getting increasingly difficult to use my computer. I'm not hugely technical with my computer, but I do know some, and have fixed many many problems before, even fixing my computer from a devestating malware virus a couple years ago myself, using only information from the internet.
Which is why I find it so infuriating that I cannot find ANY answer to help me with this problem.

Most of the time it's Facebook that's giving me a problem, but it does it on other websites too. Without going into tons and tons of detail, I have basically tried EVERYTHING I can do on my own. I have searched this problem for months and months, and always come back with nothing helpful.
I tried FF safemode in the past day or two, and it occurs there as well. I have tried everything from changing dom.max_script_run_time default, I've tried Greasemonkey, I've disabled, enabled, and disabled every script I had, I've reset FF, I've turned off the hardware accelerator, etc, etc, etc. I can't even tell you everything else that I've done because it's been such an ongoing problem. I am to the point now, that I am not going on the computer for days (even though I have things to do) because I don't want to be on it for 6 hours at a time. I want to check facebook every day for about 30 minutes, to read my mail, and chat with my friends, but it turns out to be a lesson in frustration, and I've learned to play classical music when on my computer because it calms me down. Waiting 3 hours just to check your facebook is increadibly inconvenient; something that I did at the library in 10 minutes. It doesn't just happen on FB, but that's the MAIN culprit. My Shockwave Flash also crashes ALL the time, and I've updated it several times. I've tried everything, and I just can't win. If this continues, I'm giving up on FF. I love FF. I want to use it. It used to be the best thing ever. But now, I can't do it anymore.. my patience is so stretched, that I am just done.
I am OBVIOUSLY not the only one with this problem, as there seems to be a million questions on the internet about this problem, and NOBODY can give a straight answer.
WHY?? FF you can do better than this! You MUST solve this problem! It's affecting so many people out there!
Sincerely, M

Ps.. I have a PC, Windows XPPro, FF22.0, and I had YesScript 1.9, Personas Plus 1.7,2.1, and Status-4-Evar 2013.02.16.23 (But all have been removed with the FF Reset) and none of them were the culprit because I disabled them a while ago, and still had the problem day after day.

Switched on my system this morning and found that everything has become bigger in FF. The bookmark toolbar, the font size of websites..everything has increased in size. For example when I open up dailymail website, the site used to fit on screen in such a way that I could see the main headline completely, however now half of the screen is filled up with just the header (logo etc). I have around 20 websites that I had saved on the bookmark toolbar (with shortened names) and there was space for at least one more...but now I find that the toolbar length is unable to accommodate a couple of websites...is there anyway I can fix this?

I've tried various methods of sorting tags. None of them really represents the conventional output one would consider "sorting". I've had to, for example, prefix categories of tags in order to get some semblance of order. Lately not even this works very well after going through various updates to Firefox.

Further, there doesn't seem to be anything on the Mozilla website for Firefox that addresses this question. Perhaps my library of Bookmarks is more extensive than most, and those who program the interface have never seen a need to provide this capability to sort tags. In my case, since I've used tags to introduce order and fast access to information, tags have become indispensable to that end.

Maybe the reason this capability is missing is because it is not technically feasible. I would like to know whether or not it is so I don't continue to search for a solution.
